Copper Cable

Copper cables are Tier 2, the 2nd-most common cable tier. They are capable of handling Medium Voltage (up to 128 EU-p) (up to 512 EU-p on Experimental builds), however, they suffer from losing 1 EU every 5 blocks.

They are also used in the creation of Electronic Circuits.

Shocks

(OLD)If you move too close to the uninsulated copper cable you may get an electric shock which does damage to the player so it's best to insulate your cables.

• This feature seems to be disabled in Experimental versions of IC2 (Test made in 2_2.0.277-experimental)
